1 Claim.

This invention relates to a temperature alarm, the general object of the invention being to provide simple means for sounding an alarm when the temperature in a room or building drops betemperature can be maintained uniform.

Another object of the invention is to provide means for adjusting the device so that the temperature at which the alarm will sound can be 1 regulated.

This invention also consists in certainotherfeatures of construction and in the combination and arrangement of the several parts provided to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detaikreference will be had to the accompanying drawings wherein like characters denote like or corresponding v parts throughout the several views, and in which:

Figure 1 is a front View of the device. Fig. 2 is an edge view thereof. V Fig. 3 is a section on line 33 of Fig. l. Fig. 4 is a view showing how the lever is'connected to the support.

In these drawings, the numeral 1 indicates a supporting board, which may be attached to a wall or other support by a suitable fastener, passing thru a perforation 2 in the upper end of the board. A thermometer 3 may also be attached to the front face of the board. A pair of brackets 4 is attached to the board adjacent one side thereof with their inner portions curving downwardly and towards each other, to provide seats for a battery 13. The brackets are also formed with channel-shaped outer parts 5 for receiving the flanges on a substantially U-shaped.

in when the board is supported in vertical posi tion. A contact strip 8 is-fastened to the board and contacts the lower end of p the battery and is connected by 'aconductor-Q to a bell or other alarm or signal.

A- rod 10 has one end fastened to the lower end of the board or base by the nuts 11 and the other end of the rod is formed with the upwardly extending perforated cars 12 into which extends the lower end of a lever 13 and said lower end is pivoted between the ears as shown at 14. A

bracket 15 is fastened to the board adjacent the lower end thereof and adjustably carries a wafer type of thermostat 16 against the stem of which low or goes above certain degrees so that the the lever 13 is held by a spring 17 carried by the rod 10.- The return conductor 18 is connected with the rod and therefore electrically connected to the lever. v

ly connected together by a conductor 21 and one 55 of the bracketsis electrically connected to a con I tact 22 engageable with the upper end of the battery by a conductor 23.

Thus itv will be seen that the contacts screws 19 can be adjusted in the brackets 20 and that the lever 13 is held against the thermostat by the spring 17. When the thermostat contracts due to a low temperature, the lever 13 will be moved over against the contact 19 at the right by the spring 17, so that the alarm will be given and when, thethermostat expands due to a high temperature, it will move the lever 13 over to the left to engage the other contact screw 19 and thus close the circuit to the alarm.

Thus I have provided simple means for giving an alarm when the temperature in a room or the like is too high or too low. M It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent. 7

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim. V

Having thus described my invention, what I i claim as new is: V

A device of the class described comprising a supporting member, a rod having one end connected with the. supporting member, a pair of 7 cars extending upwardly from the other end of the rod, a lever having its lower end pivoted between the ears, the upper end of the lever being of T-shape,- a bracket on the supporting member, a thermostat adjustably carried by the bracket, said bracket being located a slight distance above the rod and to one side of the lever, a spring connected to the rod and engaging the lever for holding said lever against a part of the thermostat, a pair of spaced brackets carried by the supporting member, a screw passing through each bracket for engagement by the end of they T-shaped part ofthe lever when the same is moved by the thermostat.
